反掩码即是通配符掩码,通过符号0和1通知设备应当匹配到哪位。在反掩码中,相应位为1的地址在比照中忽略,为0的有必要被查看.IP地址与反掩码都是32位的数由于跟子网掩码刚好相反,所以也叫反掩码。

(The reverse mask is a wildcard mask, which tells the device which bit should be matched by the symbols 0 and 1. In the reverse mask, the address whose corresponding bit is 1 is ignored in the comparison, and it is necessary to check if it is 0. The IP address and the reverse mask are both 32-bit numbers because they are just the opposite of the subnet mask, so they are also called reverse mask.)
